  21 # DESCRIPTION:
  22 #       Ensure that we can open the checkpointed state of a pool
  23 #       as read-only.
  24 #
  25 # STRATEGY:
  26 #       1. Create pool
  27 #       2. Populate it
  28 #       3. Take checkpoint
  29 #       4. Modify data (include at least one destructive change)
  30 #       5. Export and import the checkpointed state as readonly
  31 #       6. Verify that we can see the checkpointed state and not
  32 #          the actual current state.
  33 #       7. Export and import the current state
  34 #       8. Verify that we can see the current state and not the
  35 #          checkpointed state.
